Translation: WE ARE COMPELLED, OUR FAITH URGING us, to believe and to hold—and we do firmly believe and simply confess—that there is one holy Catholic and Apostolic Church, outside of which there is neither salvation nor remission of sins

If, then, the Greeks or others say that they were not committed to the care of Peter and his successors, they necessarily confess that they are not of the sheep of Christ; for the Lord says, in John, that there is one fold, one shepherd, and one only.

We are told by the word of the Gospel that in this His fold there are two swords—a spiritual, namely, and a temporal. […] Both swords, the spiritual and the material, therefore, are in the power of the Church; the one, indeed, to be wielded for the Church, the other by the Church; the one by the hand of the priest, the other by the hand of kings and knights, but at the will and sufferance of the priest.
